Displaying real time data from serial port

[Pedro Henriquez]

I want to use the visualization API to display, locally, data recieved from the serial port in my PC. Can anyone tell me how to incorporate the data into the charts?

You need to update the ‘data’ part of the JSON using data literal notation. See: https://developers.google.com/chart/interactive/docs/reference

You need to write an interface to your serial port in your webserver (or an interface that reads data output stored in another form, like a database) that takes the data and reformats it to the form that the Visualization API uses.  There are a few different approaches you could take from there; which you choose mostly depends on whether you want the data to be live from the serial port or whether you are retrieving stored data.

Yup thanks. For those who read later, I linked my serial port to a Google Spreadsheet (via processing) to the Visualization API. Pretty staightforward.
